Title: FLUID TRANSMISSION DEVICE
Abstract:
This fluid transmission device is provided with a pump impeller, a turbine runner, an output member, and a lock-up clutch device, which are inside an input member. The input member has a first engagement surface and a second engagement surface, which face each other in the axial direction with the lock-up clutch device therebetween. The lock-up clutch device includes: a first lock-up piston, in which friction material is adhered to a surface facing the first engagement surface; and a second lock-up piston, in which friction material is adhered to a surface facing the second engagement surface. The lock-up clutch device performs lock-up by supplying a hydraulic fluid between the first lock-up piston and the second lock-up piston so that the first lock-up piston and the second lock-up piston are separated from each other in the axial direction.
